So I was testing out CUDA miner today as it only uses the CPU (as far as I am aware) and I was getting 95.5 Mhash/s. When I use OpenCL miner however I get 110 Mhash/s. So I was wondering, does CUDA use my GPU (it would explain a fair amount) or does my GPU only generate a small amount of hashes.

Well that would make sense but im using GUI miner and there is no device thing for my GPU so I wasn't entirely sure. I was also getting some problems with my GPU when running OpenCL but it all runs fine on CUDA even with very graphics intense games. I guess 15Mhash/s is the cost of gaming on the same PC I mine with.
